This instructable shows how to make rosin out of pine sap / pitch. Rosin can be used for the following:
Electronic Soldering Flux:
Stringed Instruments:
Varnish Component:
Grip Enhancement:
Athletes (baseball, gymnastics) use rosin in the form of 'rosin bags' to enhance grip on sports equipment. If available, rosin bags provide the no-fuss source for raw rosin.
Electronic Soldering Flux:
Much like burningsuntech's instructable Make your own Eco-friendly soldering flux, you can dissolve the rosin in denatured alcohol for use as a flux.
Alternatively, you can melt the rosin directly with a soldering iron to liquify and then dip in the solder, a lead, or wire.
You can soften the rosin by adding something like vaseline / petroleum jelly to it when molten for rub-on application.
Lastly, you can take an alcohol based mixture of rosin, add water, and evaporate at room temperature to make a water-based emulsion.

Stringed instruments like violins use rosin to create grip between the bow fibers and the instrument strings. You can remelt the solder using a deep fryer and then pour it a c-shaped wooden mold.
Varnish Component:
Rosin can be used as a component in varnish, for example when added to linseed oil.

Signing UpStep 1: Collect
In this step, collect pine sap / pitch.
Locate a pine tree with 'wounds' from tree trimming. These contain the pine sap / pitch mixed with wood chips, pollen, bugs, and dirt. Use a butter knife to scoop the sap / pitch into an appropriate container. An appropriate container should be made of glass or of high density polyethylene plastic (HDPE). This type of plastic can withstand strong solvents like acetone and is generally marked with a '2' in the recycling symbol.

A question: can I use regular pine sawdust to obtain rosin?
